Auto-configuration of network devices

A network device being connectable to a data communication network, the network device comprising:

• at least two device components, each device component including a communication interface for communicating data, the communication interface being accessible by using an internal network address associated with the communication interface;
• an address translation device including an internal interface for communication with the communication interface of each of the at least two device components and an external interface for communication with an external device different from the network device;
• and
• the address translation device being configure for receiving external data from the data communication network and an target identifier identifying a first device component out of the at least two device components,
• the address translation device being further configured for determining, based on the target identifier, the internal network address associated with the communication interface of the first device component, and
• the address translation device being further configured for forwarding the external data to the first device component by using the internal network address of the first device component.
